( Figs. 12 E; 21G–I; 30)

Holotype: BMNH #809770 (specimen examined)

Type location: Chile

= Satyrus hypsophila Reed, 1877

Holotype by indication ( ICZN Art. 12.2.7): Plate II fig. 8 in Reed (1877)

Other combinations:

Faunula leucoglene — Heimlich (1972); D'Abrera (1988, p. 799); Peña & Ugarte (1997, p. 281); Lamas & Viloria (2004, p. 216)

Distribution. Found in Chile from southeastern Atacama Province south to northeast Araucanía Province and in Argentina from northern La Rioja Province to Northwestern Chubut Province from December to early March at 900–3850m ( Fig. 30). They can be caught near exposed rocky areas, but can be difficult to approach ( Elwes 1903).

Diagnosis. Similar to T. patagonica , but without ventral side hindwing ocelli. Both dorsal side and ventral side chocolate to dark coffee brown with a slightly lighter brown postmedian band on the ventral side of the hindwing. Apical ocellus on the ventral side of the forewing is black and spans M1-M3, bearing a large, round, white pupil between M1-M2. Females have a white ocellus on the dorsal side of the forewing between M1-M2 similar to the white pupil on the ventral side. Males have heavy androconia in a wide stripe along the median of the forewing. Antennal clubs round and palps with a short, oval terminal segment. Foreleg tarsi with five segments in the females and three in the males.

Redescription. Head: Antennae 7–8mm with dark coffee scales and a longitudinal stripe of white scales, terminating in a round club. Eyes round and naked, length approximately 1.2 times width. Palps cream to vanilla with coffee ventral side piliform scales in the females. Males with taupe to coffee palps. Terminal segment oval and about one-sixth the length of the second segment.

Thorax with iridescent black scales and coffee piliform scales. Abdomen taupe ventrally to dark chocolate dorsally. Foreleg tarsi with five segments in the females and three in the males. Female tarsi bear a pair of dark amber spines at each joint. Midlegs and hindlegs with four rows of black spines on the tibia and tarsus.

Forewing ( Fig. 12 E): Wingspan 24–28 mm. Termen slightly convex and the distal end of the discal cell sinuous. Males with a heavy androconial patch that extends from R5 to just past CuA2 and into the discal cell from the cubitus nearly to M2. Dorsal side dark chocolate to dark coffee brown, the females lighter than the males with the fringe scales chocolate brown. Females with a white ocellus between M1-M2 that may be surrounded by a patch of dark chocolate scales. Postmedian band appears in lighter specimens as two patches of rust orange between M3-CuA1 and CuA1-CuA2. Ventral side similar in color to the dorsal side with the postmedian band appearing as a lighter brown to rust orange triangle surrounding the M1-M2 ocellus that is widest at the costa and terminates at CuA1. Apical ocellus is round and black, extending from M1-M3 and with a single, large, white pupil between M1-M2.

Hindwing ( Fig. 12 E): Wing rectangular, termen straight to slightly convex and entire. Dorsal side similar in color to the forewing with the postmedian band visible in lighter specimens as patches of rust orange between M3- CuA1 and CuA1-CuA2. Fringe scales are as in the forewing and long piliform scales appear at the base and over the discal cell, extending to the median and toward the inner margin. Ventral side similar in color to the dorsal side. Postmedian band lighter brown than the rest of the wing with the proximal edge scalloped and the distal edge indistinct, extending to the termen.

Male genitalia ( Fig. 21 G–I): Uncus wide at the base, narrowing to an acute terminus, and about equal in length to the tegumen. Gnathos acute and a little more than half the length of the uncus. Pedunculus U-shaped and wide. Saccus U-shaped and about equal in length to the gnathos. Valvae widest at the median, narrowing toward the proximal end, forming an acute triangle and narrowing slightly toward the distal end, terminating in a U-shape. Aedeagus nearly even in width throughout, the proximal end slightly wider with a truncate terminus.
